Yanfei Lei created FLINK-23399: ---------------------------------- Summary: Add a benchmark for rescaling Key: FLINK-23399 URL: https://issues.apache.org/jira/browse/FLINK-23399 Project: Flink Issue Type: Improvement Components: Runtime / State Backends Affects Versions: 1.14.0 Reporter: Yanfei Lei
We notice that rescaling is not covered in the current state benchmark, so we'd like to introduce a benchmark for rescaling in flink-benchmark. The benchmark process is: (1) generate some states, (2) change the parallelism of the operator, and restore from these states generate before. The implementation of this benchmark is based on {{RocksIncrementalCheckpointRescalingTest}}, and *_AverageTime_* is used to measure the rescaling performance on each subtask. And this benchmark does not conflict with RocksIncrementalCheckpointRescalingBenchmarkTest in [PR|[https://github.com/apache/flink/pull/14893]]. Compare with RocksIncrementalCheckpointRescalingBenchmarkTest, this benchmark supports testing rescaling on different state backends, and has a finer granularity. -- This message was sent by Atlassian Jira (v8.3.4#803005)
